First calculate volume of the cylindrical container: Pi * R2 * H; where Pi is 22/7 or 3.147, R is the radius and H is the height of the container.
Vol of the cylindrical container: 3.147 * (3.25/2) * (3.25/2)* 5 = 41.55 inch 3
Volume of the shaker using the above principle:
3.147 * (1/2) * (1/2) * 1.5 = 1.18 inch 3
Number of times it can fill the salt shaker will be the ratio of the volumes:
= Volume of the cylindrical container divided by the volume of the shaker = 41.55 divided by 1.18
Answer is 35 times if rounded in absolute number.

Answer:
17 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 2700° , then
180°(n - 2) = 2700° ( divide both sides by 180° )
n - 2 = 15 ( add 2 to both sides )
n = 17
The polygon has 17 sides

Answer: 4.5pi</h3>
This is the same as 9pi/2 or (9/2)pi
===================================================
Explanation:
A full circle has area
A = pi*r^2
Since the radius is r = 3, we know that
A = pi*r^2
A = pi*3^2
A = pi*9
A = 9pi
is the area of the full circle with radius 3.
But we have a semicircle here, so we need to cut this area in half
9pi/2 = (9/2)pi = 4.5pi
